Subaru communications chief Mike McHale told us that Subaru in the U.S. had to give up some of its allocation of Impreza compact hatchbacks and sedans to get the even-more popular XV Crosstrek instead.

The company continues to post rising sales numbers, but already, the Crosstrek is the fourth most-popular Subaru sold here since going on sale last September.

So far, in the first six months of the year, Subaru has sold almost as many Crosstreks (25,090) as Impreza sedans and hatchbacks combined (29,553).

The Impreza WRX, still built on the last-generation Impreza, added an additional 9,553 units.

Subaru's two most popular vehicles in the U.S. are the Outback and Forester crossover.

The 2014 Subaru XV Crosstrek Hybrid will officially launch late this year.

Pricing and its final EPA gas-mileage ratings haven't yet been released.
